DANIEL I WIRT, OF OAK GROVE, VIRGINIA lMPROVEMENT IN C ORN-SHELLER SEPARATORS.

Specification forming part of Letters Patent No. 2l4,542,dated April 22, 1879; application filed August 2, 1878.

To all whom it may concern:

Be it known that I, DANIEL P. WLRT, of

Oak Grove, Westmoreland county, Virginia,

having my improvement; and Fig. 2, an end view, the shields removed.

A is the cylinder, supported by legs B, having a chute, a, for discharging the cobs, and a funnel, I), through the open lower end of which the corn and chaff pass downward.

A frame, 0, below the cylinder A, supports an ordinary fan or blower, D, in front of which are suspended two sieves, e c, to which the vibratin g motion is imparted in any suitable manner.

An inclined shield, h, extends downward from the front end of the sieve c, and another shieldfi, in front of the shield h,projeets upward above the shield e, for the purpose described hereinafter. The upper sieve is somewhat larger in its meshes than the lower.

The corn and chafl which fall from the hopper cl are met by ablast of air from the fan D, which blast is of such strength as to carry off not only the lighter particles of chaff, but also the broken bits of cob, 820., which are arrested by the upper sieve, the motion of which facilitates the discharge of the lighter material, while the grains of corn pass to the lower sleve.

Suitable chutes from both chambers may carry the different qualities of grain to different receptacles.

By this means the chaff is separated without losing the imperfect grains, or mixing them with the perfect kernels.

In order to adapt the separator to the form of sheller represented in the drawings, which is extensively used, I arrange the fan, shields,

and sieve upon a frame, (3, so that the structure may be sold as an attachment capable of being applied, with little or no change, to the shellers in use.

1 elaiml. The combination, with the sheller having a grain-discharge funnel, b, of the fans D, shieldsh 'i, and suspended vibrating sieves e e, the latter being inclined, and both being arranged to be traversed by the air-currents, and all arranged on the detachable frame (3, as set forth.

2. The combination of the fan D, sieves e c, shields h i, and detachable supportilng-franie 0, adapted to the frame of the sheller, as set forth. I

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
